As a pesticide handler, which route of exposure should be of the greatest concern?

While dermal exposure is indeed a significant concern for pesticide handlers, the route of exposure that should be of the greatest concern is inhalation. Inhalation can lead to immediate and acute effects due to the high absorption rate of airborne chemicals through the respiratory system. Pesticides in aerosol or vapor form can quickly enter the bloodstream and impact vital organs, making it crucial for handlers to take precautions to minimize inhalation exposure.

Ocular and oral exposures also pose risks but are generally not as immediate or systemic as those from inhalation. Dermal exposure is notably a concern as well, especially considering the potential for skin absorption, but inhalation remains a primary concern due to its rapid effects and the challenging nature of controlling airborne contaminants compared to other exposure routes. This highlights the importance of using proper personal protective equipment (PPE) and working in well-ventilated areas to reduce inhalation risks effectively.
